title: Aortocaval fistula after endovascular stent-grafting of abdominal aortic aneurysm.
abstract: The authors present a case report of a 79-year-old man with insufficient cardiac contractile function who underwent endovascular stent-grafting for an abdominal aortic aneurysm. Thirty months later, the aneurysm ruptured into the inferior vena cava and subsequently formed an aortocaval fistula caused by migration of the stent-graft. Urgent secondary endovascular stent-grafting successfully excluded the blood flow into the vena cava. Endovascular stent-grafting is deemed suitable for treating this serious disorder, especially in severely debilitated or compromised patients who might not withstand a standard surgical intervention. Furthermore, in patients with previous stent-grafting, since the primary stent-graft makes repair by open surgery more difficult, a secondary endovascular intervention is recommended if feasible.
